PRIMER FOR GAS-ENGINES.

Application filed January 14, 1915.

` To all fro/tom t may concern.'

Be it known that I, EDWARD H. BAUER, a citizen of the United States, residing at lVashington, District of Columbia, have invented certain nevv and useful Improvements in Primers for Gas-Engines, of which the following is a full, clear, and exact specification.

This invention Vrelates to internal com bustion engines and especially to means for' gas saver controlled' by a single valve operated by the driver orlchauffeur.

A further'object is to make the primer more effective by taking ,the gas or fuel directly from the bottom of thecarbureter.

Another object is to heat the additional air admitted for the purpose of saving fuel.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification and then more specifically defined in the claims at the end of the description.

In the accompanying drawings wherein similar reference characters are used throughout the several views to designate corresponding parts: Figure l is a side View of the carbureter, manifold and exhaust pipe of an internal combustion engine, with my combined priming and gas saving device applied thereto.v Fig. 2 is a detailed sectional view, on an enlarged scale, of the single valve which controls the primer and gas sirven-said valve being shown in the position in which both the primer and gas i saver are cut off. Fig. 3 is a similar view of the valve in a position to permit priming. Fig. 4 is a similar view of the valve in the position for admitting an extra supply of air for the punposeof saving gas or fuel, and Fig. 5 is a sectional view through the valve taken at right angles to the sections shown in Figs-2, 3 and 4, showing the tapered construction of the valve plug and the spring for taking up wear and holding *said valve firmly to its seat.

.Referring to the drawings, A designates Specification of Letters Patent.

a carbureter of known construction towhich fuel or gas is supplied from a tank (not shown) via pipe a, and from which the mixture of air and gas is delivered to the manifold B by the connectionb. A pipe C leads from the bottom of the carbureter A to a three-way valve D from which a pipe E connects to the manifold B, and another pipe F extends close to the exhaust pipe Gr, being preferably although not necessarily coiled about the same, as shown at f. If desired a T-coupling may be secured at the upper end of the pipe E and said pipe made to communicate with the manifold at a plurality of points instead of at one point as 'shown in the drawing. The plug d of the valve is tapered, as shown in Fig. 5, and is provided with a spring CZ for holding it firmly to its seat and taking up wear. Said valve plug is connected by a universal connection H te a rotatable controlling rod K extending through the dash L of the vehicle or car. Said rod may be fitted with an operating arm or handle M and any suitable indicating means (not shown) may be employed for showing the different positions of the valve. It will be understood, of course, that the operating handle is placed in convenient reach of the chauffeur or driver. The pipe C enters port d2 of the valve, while the pipes E and F connect with the ports d3 and d4, respectively, of said valve, see Figs. 2, 3 and 4. As illustrated in Fig. 2, the valve plug is turned so as to cut off communication from both. of the ports cl2 and (lt with thel the valve when the engine is r'unning and there is no occasion for reducing the amount of gas used in the mixture.

When it is desired to prime the engine, the valve plug (l is turned to the position illustrated in Fig. 3, establishing communication' between the pipes C and E via the ports d: and d3, the port d4 and pipe F being cut ofi'. The gas or fuel may then pass from the bottom of the carbureter, where aid fuelor gas is richest, directly into the manifold by way of pipe C, valve D and pipe E. The valve being in this position and the engine, of course, not running, to prime the engine, all th'at is necessary is to operate the starting crank a sufficient numberof times to Efe?) cause gasolene to be sucked up into the severalv cylinders. The valve is then turned to y@Imperative position, as shown in Fig. 2, and the engine is ready to ybe cranked and 5 started and it has been demonstrated that by the use oi' my primer the engine will start after such priming on irst turn of the crank.

When ii is desired to save gas or fuel, the valve plug d is turned to the posit-ion illustrated in Fie'. 4i, establishing communication between pipes i? and l via ports d'4 and d3, and cutting off pipe C and port (Z2. ln this position of the valve, additional air is admitted to the manifold through pipe l?, valve D and pipe E. It will be understood that the outer end of the pipe F is open. and that said pipe extends near to the exhaust pipe G of the engine, being preferably coiled about the same, as shown, for the purpose of heating the air before it reaches the manifold, if so desired. Furthermore, the amount of opening for admitting additional air for the purpose of saving gas can very 25 readily be regulated as will be apparent. 'Likewise in a similar manner the amount of opening oi the valve in priming may also be readiiy regulated or adjusted so as to give a lean or rich mixture, as desired. Furthermore, in the event oi' the carbureter getting out oi order, this device may be so adjusted as to be used temporarily as carbureter, that is it may be adjusted so as to admit nach an amount of gas that will mix with the air coming through the air inlet of the earbureter as to produce the proper mixture to run the motor and enable the operator to .reach a point where the carbureter may be repaired. it will be understood, oi course, -iw .f at in so operating the device the maniioid encules-.in a sense the mixing chamber, the arr erderingr the manifold through the careter and the gas entering the nianifoid 'rough this attachment. it will also be rstood that in the use of this device for pi ming, such act cleans the carburetertakout any Water or sediment that may have collected therein and likewise keeps the bureter in goed condition.

Having thus described my invention what pipe and a carburcter, of a three-way valve,

a pipev leading from one port of the valve to the carbureter, another pipe leading troni another port of the valve to the manifold,

an open air intake pipe extending near to the exhaust pipe and connected to the third port of the valve, and means for operating said valve to selectively establish eommunication between either the air .intake pipe or the pipe leading from the carbureter and the pipe leadingl to the manifold.

2. rlhe combination with the manifold ot' an internal combustion engine, an exhaust pipe and a carburetor, of a three-way valve, a pipe leading from one port oit the valve to the carburetor, another pipe leading from another port of the valve to the manifold, an open air intake pipe extendingv near to the exhaust pipe and connected to the third lport of the valve, and means for operatingsaid valve te selectively establish .communication between either the air intake pipe or the pipe leading from the carbureter and the pipe leading to the manifold, and :for ciosing the three pipes when desired.

3. The combination with the manifold of'. an internal combustion engine, exhaust pipeand a carbureter, of three-Way vaive, a pipe leading from one port of the valve the carbureter, another pipe ,ieading from another port ei the valve to the manifold, an

open air intake pipe extending near to theexhaust pipe and connected to the thirdport of the valve, and means extending within reach from the drivers seat for operating said valve to selectively estabiish commnni cation bet veen either the air intake pipe the pipe leadung from the carbureter the pipe leading to the inanitoid.

in testimony whereof have signed mi name to this .speeiication in the presence of two attesting witnesses.,
